JACOB SOHERFFIUS, OF WINONA, MINNESOTA.

SYSTEM OF VENTILATION AND HEATING.

SPECIFICATION forming part of Letters Patent No. 495,568, dated April 18, 1893.

Application filed October 24, 1892. Serial No. 449,793. (No model.)

To all whom t may concern,.-

Be it known that LJACOB SoHEEEE1Us,a citizen of the United States, residing at TVinona, in the county of I'Vinona and State of Minnesota, have invented certain new and yuseful Improvements in Systems of Ventilation and Heating; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to improvements in Ventilating and heating buildings, and it is designed more particularly as an improvement upon the construction disclosed in my application bearing even filing date herewith. In my said contemporary applicatlon I have provided means whereby fresh air may be heated en route to the apartments, and said apartments may be discharged of the stale air, and whereby with slight adjustment the air from the apartments may be conducted back to the heating agentr to be reheated and again conducted to the apartments.

In my present application, in addition to providing for the simultaneous heating and ventilation of the apartments, and the high heating of said apartments, I have provided means whereby fresh air may be conducted to the apartments without subjecting the same to heat which is a highly important desideratum.

W'iththe foregoing in view the novelty of my present invention will be fully understood from the following description and claims when taken in conjunction with the annexed drawings, in whichz- Figure l, is a horizontal section taken through the basement of a building embodying my invention. Fig. 2, is avertical section taken in the plane indicated by the line az, oc, of Fig. l, with the pivoted dampers shown in their approximately vertical positions, and Fig. 3, is a similar view taken in the plane indicated by the line y, y, of Fig. l, with the pivoted dampers in their approximately horizontal positions.

Referring by letters and figures to said drawings :-A, indicates a building which may be of any approved construction; and B, indicates a furnace arranged in a furnace chamber C, which chamber is preferably built or placed in the basement of the building as shown. f

Formed in one of the side walls of the furnace chamber C, and preferably adjacent to the bottom thereof, is a port ci, which communicates with a chamber D, which for convenience of description I will term a fresh air chamber.

E, E', indicate the flues for leading the heated air from the furnace chamber to the apartments to be heated, which flues are connected with the furnace chamber by the ports f, f', and with the apartments to be heated by the ports e, e' which latter ports are preferably arranged adjacent to the ceilings, so that the heated air will displace the air in the room and force the same down and out as will be presently explained.

F, F', indicate the flues for leading the heated and impure air from the apartments, which fines are connected with the fresh air chamber by the ports g, g', and are connected with the apartments by the ports h, as shown.

Formed in the party wall b, of the flues F, F, is a port d, anda port cl', which port d, is controlled by the pivoted damper G, and formed in the wall of the flue F', opposite to the party wall b, is a port t, which communicates with the uptake H, and is controlled `by the pivoted damper M, which is adapted to be manipulated bya crank j, ahand wheel or other suitable device. The port d', serves to lead the fresh air from the flue F', to the ue F, when the pivoted dampers are in the position shown in Fig. 3. v

Leading from the open air to the lower end of the uptake H, which is preferably arranged at the side of the smoke flue or chimney c, is

the induction fiue N, through which fresh air is led into the building.

As better shown in Fig. 2, of the drawings the dampers G, M, are connected by a link m, so that when the damper M, is moved, the damper G, will be moved in a corresponding direction. These dampers G, M, are of such a size that when in their approximately vertical position as shown in Fig. 2, the damper G, will close the port d, and the damper M, will close the port i.

As thus far described the construction of my present invention is the same as that dis- IOO closed in my contemporary application and is designed to be operated in the same manner and to the same purposes as will be presently set forth.

As before stated the general object of the present invention is to provide means whereby fresh air may be conducted to the apartments without subjecting the same to the action of heat; and to this endl have provided the horizontal wall p, adjacent to the lower end of the flue E', the port q, in the party wall of the dues E', F, the port r, in the party Wall of the iiues E, E', and the port s, in the party Wall of the flues E', F.

Mounted in suitable guides or ways within the flue E, is the slidable damper P, which is designed and adapted to control the port 7'; and mounted in suitable guides or ways within the flue F, is the slidable damper Q, which is designed and adapted to control the port g', and is connected with the damper P, by the sprocket chain R, as shown. This sprocket chain R, as better shown in F1g. 2, of the drawings takes up through the iiue E, to the second story where it takes over the sprocket wheel t, fixed on a rotatable shaft u, and a sprocket wheel o, fixed on a rotatable shaft w, and the said chain then takes down through the iiue F, to the damper Q, to which it is connected.

Both of the shafts u, and w, which extend through the wall into the apartment, are pro vided with cranks, hand wheels or the like whereby the sprocket wheels may be rotated to raise and lower the dampers; and by reason of the said dampers being connected by the chain R, it will be seen that when the damper P, is raised to open the port r, the damperQwill be lowered to close the port g', and vice versa, a suitable indicator being preferably arranged in the apartment to indicate the respective positions of the dampers.

Mounted in suitable guides or ways within the Hue E', is a slidable damper S, and mounted in guides or Ways within the flue F', is a slidable damper T, which is designed and adapted to control the port c and is connected with the damper S, by the chain U. This chain U, takes up the flue E', to the third story of the building where it passes over a sprocket wheel l, on a rotatable shaft 2, and a sprocket wheel 3, on a shaft Lt, and it then takes down the flue F', to the damper T. The shafts 2, and 4, are extended through the wall into the apartment so as to enable a person in the apartment to operate the dampers S, T. Thus it will be seen that a person upon the second floor may operate the dampers P, and Q, and a person upon the third iioor may operate the dampers S, and T, and as the dampers P, and Q, affect only the second floor and the dampers S,and T,only the third floor, it will be seen that a person upon either of the floors may readily regulate the temperature of the same without affecting that ofthe other floors.

In practice when it is desired to ventilate and heat the building, and heat the fresh air en route to the apartments, the ports r, s, are closed, and the ports g, g', consequently opened, and the dampers G, M, are adjusted to the positions shown in Fig. 3, so that the fresh air will take through the iiue N, the port fi, the flue F', the port d', the ports g,g, the fresh air chamber G, the port a, the furnace chamber C, the ports f, f', the ues E, E', the ports e, e', the apartments, the ports h, the liues F, F", and the port t', to the uptake H, through the medium of which it is conducted to the open air.

lVhen it is simply desired tohighly heat the apartments, the ports o, s, are closed, and the ports g, g', are opened, and the dampers G, M, are adjusted to the positions shown in Fig. 2, so that the air will pass or circulate from the furnace chamber C, through the ports f, f', the flues E, E', the ports 7l, the dues F, F', the ports g, g', the chamber C, and the port a, back to the furnace chamber where it will be reheated and again conducted to the apartments.

When it is desired to admit fresh air (cold) to the upper or third story apartment without heating said air; the dampers G, M, being in the position shown in Fig. 3,the damper S, is raised to open the port s, and the damper T, is lowered to close the port g, when fresh air will pass from the flue N, through the port i,

the flue F', the portv d', the flue F, the ports,

the iiue E', the apartment, the port 7L, the iue F', the port t', and up the uptake, to the open all'. l

When it is desired to admit fresh cool air to the lower or second story apartment, the dampers G, M, being in the position shown in Fig. 3, the port s, is closed, and the port g, consequently opened while the port r, is opened, and the port g', consequentlyclosed, so that the fresh cool air will pass through the induction flue N, the port 1I, the flue F', the port d', the flue F, the port q, the port fr, the flue E, the port e, the apartment, the port h, the flue F, the flue F', the port t', and up the uptake to the open air.

When it is desired to admit fresh cool air to both apartments at once, the ports o", and s, are both opened and the ports g, g', both closed so that the air may pass directly into both of the fines E, E.

Although I have in some instances specili- IOO cally described the construction and relative 1 arrangement of the several elements of my in its side Wall remote from and independent of the furnace chamber, for the admission of cool fresh air, an adjustable damper for controlling the said port r, and a suitable means for operating said damper, substantially as specified.

2. The combination with afurnace chamber i having an induction port ct, for the entrance of air to be heated, a flue communicating` with the furnace chamber and the apartment to be heated, and having a port 1^,in its side Wall for the admission of fresh cool air, a flue F, having an inlet port d', for the admission of fresh cool air, an outlet port q, and an outlet port g', and a suitable means for conducting air from the outlet port g', of said flue to the furnace chamber; of'a damper P, controlling the induction port r, in the fine communicating with the furnace chamber and the apartment to be heated, a damper Q, controlling the outlet port g', of the flue F, and a suitable means for operating said dampers so that when one is opened the other will be closed, substantially as specified.

3. The combination with a furnace chamber having an induction port for the entrance of air to be heated, a flue communicating with the furnace chamber and the apartment to be heated, and` having a port r, independent of the furnace chamber for the admission of cool fresh air, a iiue F having an inlet port df for the admission of fresh cool air an outlet port q, and an outlet port g', and a suitable means for conducting air from the outlet port g of i andthe apartment to be heated, and a damper controlling the outlet port g of the ue F; of the rotary shafts extending into the apartments be heated, the sprocket Wheels fixed on said shafts, and a` sprocket chain taking over the Wheels and having its ends connected to the dampers, all substantially as and for the purpose set forth.

4. The combination With a furnace chamber, a fresh air chamber, a port d connecting the furnace and fresh air chambers, the iiues F, F', having the ports g, g,\the ports d d', formed in the party Wall of said flues, the port z', formed in the Wall of the flue F', the induction ue N, communicating with the port t', the uptake leading from the induction flue, and dampers controlling the ports d, t', of the flues communicating with the furnace chamber and the apart-ments to be heated and having the ports r, s, the port q, formed in the party Wall of the iiues E', F, and communicating withthe port r, dampers controlling the said ports "r, s, and dampers controlling the ports g, g', of the lues F, F', the said dampers being so connected together that when the port 1", is closed, the port g', will be opened and vice versa, and When thcrport s,

is closed, the port g, will be opened and vice Versa, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
